1. A method for manufacturing a part for an aircraft seat characterized in that it comprises:
a step of positioning a heating frame around a stacked structure comprising a foam core, a first cover and a second cover made of a thermoplastic material and arranged on either side of the foam core, a first film of hot melt glue between the first cover and the foam core and a second film of hot melt glue between the second cover and the foam core,
a step of locally heating at least one edge of the stacked structure with the help of a heating frame,
a step of externally heating the entire stacked structure,
a step of placing the stacked structure inside a thermoforming mold equipped with cutting punches,
a thermoforming step by closing the thermoforming mold and applying vacuum inside the thermoforming mold, so as to shape the first cover and the second cover, heat seal at least one edge of the first cover and at least one edge of the second cover to one another, bond the first cover and the second cover to the foam core, and cut the stacked structure along the circumference thereof with the help of the cutting punches simultaneously during the same step.
